Abstract

The invention discloses a flexible beam multi-point driving photovoltaic tracking support and a photovoltaic device, the photovoltaic tracking support comprises a support main body and a driving assembly; the support main body comprises a plurality of stand columns which are arranged side by side at intervals, rotatable oblique beams are arranged on the stand columns, and a plurality of support cables which are arranged side by side at intervals are arranged between two adjacent oblique beams; the driving assembly comprises a driver, a transmission device and rotating devices; the rotating device is arranged between each stand column and the oblique beam on the stand column, and the driver is in transmission connection with each rotating device through the transmission device; the photovoltaic tracking support adopts support cables to form a flexible beam structure, the terrain adaptability is improved, the steel consumption is low, the installation is convenient, the overall damping ratio of the support is increased, and wind pressure resonance can be avoided; the rotating devices can form multi-point drive, free rotation of the oblique beams can be limited, the stability and torsion resistance of the support are enhanced, and it is guaranteed that all the oblique beams act consistently, the tracking precision is high, meanwhile, the multiple rotating devices can provide larger driving force, and the single-machine installation capacity is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic equipment, in particular to a flexible beam multi-point driven photovoltaic tracking support and a photovoltaic device. Background technique [0002] With the rapid development of the photovoltaic industry in recent years, major photovoltaic support manufacturers have successively launched various photovoltaic supports, including ground fixed supports, roof distributed supports, ground single-axis tracking supports and dual-axis tracking supports, etc. The above-mentioned tracking supports , the driving device and rotating device are added, so that the photovoltaic support can track the sun in real time to obtain the maximum power generation. [0003] At present, most of the photovoltaic tracking brackets in the industry adopt the rigid beam design. The photovoltaic modules are fixed on the rigid main beam through secondary beams, pressure blocks, bolts and other components, and then drive th...

Problems solved by technology

[0003] At present, most of the photovoltaic tracking brackets in the industry adopt the rigid beam design. The photovoltaic modules are fixed on the rigid main beam through secondary beams, pressure blocks, bolts and other components, and then the rigid main beam is driven to rotate through the driving parts. This installation and fixing method exists. Large amount of steel, high cost, difficult installation, high structure center of gravity, poor terrain adaptability, etc., and except for the driving position, other rotating parts can rotate freely. When this structure is subjected to a large wind load, the rotating parts are easy to rotate freely , causing the bracket to twist, causing havoc
